UE4 加速Setup.bat

下载了UE4的源码后，运行Setup.bat时下载速度比较慢，可以通过开启多线程的方式下载，速度会快很多。

从文件内容可以看出，实际上是运行的\UnrealEngine-release\Engine\Binaries\DotNET\GitDependencies.exe

它的用法是：

Usage:
   GitDependencies [options]

Options:
   --all                         Sync all folders
   --include=                 Include binaries in folders called 
   --exclude=                 Exclude binaries in folders called 
   --prompt                      Prompt before overwriting modified files
   --force                       Always overwrite modified files
   --root=                 Set the repository directory to be sync
   --threads=                 Use N threads when downloading new files
   --dry-run                     Print a list of outdated files and exit
   --max-retries                 Override maximum number of retries per file
   --proxy=   Sets the HTTP proxy address and credentials
   --cache=                Specifies a custom path for the download cache
   --cache-size-multiplier=   Cache size as multiplier of current download
   --cache-days=              Number of days to keep entries in the cache
   --no-cache                    Disable caching of downloaded files

开启多线程的方法就是:set PROMPT_ARGUMENT=--prompt --threads= xx

(其中xx表示数量).
